  The CfA team revealed that it is a type II supernova.  The recession
velocity deduced from the H-alpha emission peak (from the spectrum on
the website*) is about 14000 km/s, which is consistent with the NED
value.  The SN can be a very luminous event, or the host galaxy has a
peculiarly large proper motion relative to the Hubble flow.  The
apparent size of the galaxy seems large, so the latter possibility
should be considered.

  The CfA team has revealed that it is type Ia supernova, about a week
before maximum on Apr. 3.28.
